Marc Paraguya: The Night Shift Chess Machine
Marc Paraguya, known on the scoreboard as marc_paraguya, is an online chess veteran who has been grinding since 2009 and shows no signs of stopping. At home in every time control, he now favors bullet chess, where flags flutter, pieces fall, and reflexes do the thinking. His career is a monument to volume: tens of thousands of games, a repertoire built on the London System and the Caro-Kann Defense, and a peak performance hour of 3 A.M.
The Perfect Opening Act
Every career deserves an origin story this clean. In October 2009 Marc entered daily chess and did not lose for months. His first 36 recorded games were all wins, a flawless run that carried his rating past 2300 by March 2010 and left him looking like a future title contender. Then the calendar turned, reality arrived, and January 2012 delivered a 21-game losing streak with zero wins as an early tuition payment.
The Blitz Decades
If Marc has a homeland, it is the blitz board. He has logged roughly 15,000 blitz games, once squeezed 888 of them into September 2015 and a monstrous 981 into October 2025, and still pushed his peak to 2678 (2025-10-08) along the way. His win-loss column there sits almost exactly even, which says less about him than about his habit of playing everyone, forever. Rapid chess has been kinder lately, with the 2026 climb peaking at 2551 (2026-08-25), and he has even cracked 2200 in bullet at 2203 (2026-08-24).
The Repertoire: Rock Solid, Occasionally Unhinged
As White, Marc is a London System loyalist, and his Poisoned Pawn Variation has consumed nearly a thousand blitz games on its own. He also rides the Amazon Attack: Siberian Attack and the Australian Defense setup, and the Döry Defense has been his rapid cash register at better than 70 percent. As Black, he is a Caro-Kann devotee of the first order, over a thousand blitz games deep, though the side door matters too: he is a perfect 6 for 6 with the Alekhine Defense in bullet, dabbles in the Amar Gambit, and once played the Barnes Defense in daily chess 32 times for exactly 2 wins, which is either tragedy or committed performance art.
Rivals and Final Bosses
No one has faced Marc more than Kenneth Sumile, who leads their 285-game war 151 wins to 119, a rivalry that may outlive the site itself. Mikhail Tal has been a generous training partner, dropping 63 of 104 meetings, while rudolf_perez learned what happens when you skip the scouting report, losing 39 of 57. On the painful side of the ledger live Kevin_Arquero (16 wins, 70 losses) and kalorenzo_pcap (3 wins, 34 losses), two names that probably make Marc check the queue twice.
The Mind of a Night Owl
- Peak hour: 3 A.M. His best win rate arrives in the smallest hours. Either he works nights or he dreams in rook endings.
- Calendar science. Tuesdays are his best day of the week. Wednesdays, politely, are not.
- Tilt factor: 138. Delightfully, that is also the exact length of his longest losing streak. Marc does not tilt, he tectonically shifts, and then he keeps queuing.
- Impossible to finish. An 85 percent comeback rate, an early resignation rate under 4 percent, and one-sided losses in fewer than 4 percent of games mean no win is real until Marc signs off on it.
- The long game. More than 80 percent of his games reach an endgame, his average win runs about 78 moves, and his first capture usually waits until move 7. Patience, then violence.
- Rook knocker. Over 15,000 of his checks have been delivered by rooks, his favorite door-knocking piece.
- The 1263 bunker. In April 2020 he played 279 daily games, lost 238 of them, and then defended a rating of 1263 like a rented apartment for over a year.
Legacy
Marc Paraguya is living proof that chess improvement is not a staircase but a treadmill set to maximum incline. He has survived a 138-game losing streak, a historic daily chess collapse, and a rival literally named oblivion, and he still shows up at 3 A.M. to hit the queue again. The clock may say whatever it likes. The board knows Marc is coming.
